I'm thinking this might be because of the tire weight, maybe. Not sure. If the tires are really heavy, you might have to gear down to compensate. The smaller front & larger rear sprockets lower the gearing, which will mean less top end usually. Not all the time, depends on the bike i guess. Mine seems to pull really well with the stock gearing, i need to get one of my cop buddies to clock me and i'll let ya' know. [img]i/expressions/face-icon-small-shocked.gif[/img]

 

The reason for gearing down is because when you increase the tire size you will have more top end and less low end. Tire size is alot like changing gears. If you go down to a 15 tooth sprocket you will loose top end but gain more on the lower end. So many people will drop down a tooth or 2 on the front sprocket to get back the low end you loose with the larger tires. I run a 14 tooth front sprocket and it still has more top end with the 22s than the factory 16 tooth with the 20 inch tires.

 

my brother bought a pair on saturday, wow! could barely slide it around on wet grass, can't wait for the snow to see how they do, looks like i may hafta buy a pair [img]i/expressions/face-icon-small-tongue.gif[/img]

I can't say what they do in the snow, but it should be interesting. [img]i/expressions/face-icon-small-cool.gif[/img]

 

you got to love thoughs mud machines. Nice bomber Bill

 

all this talk about these mud machine tires I just had to order some for myself. Will let ya know what I think latter.

 

The Mud Machines go great on any terrain. They are awesome for trail hill climbing, and they hookup in almost any kind of slop. I ran them for 1/2 a summer when I trail rode my Raptor, and I wouldn't buy another tire on the market over the Mud Machine for trail riding. If you are strictly a trail rider/hill climber and ride in alittle mud....the Mud Machines are your best bet for rubber.

 

I ran mine in the WV snow last winter and they did great. You won't be disappointed with the Mud Machine A/T. I assure you they are the best trail(mud or snow) tires you will get.

The best air pressure to run is about 2-3lbs....then when you get to a rough or rocky hill climb....let down to 1lb and hold on tight because you are going to be getting monster traction. Also in deep snow, air down to about 1lb.
